MOTORCYCLE-WINDSHIELD.

Application filed March 29, 1919. Serial No. 285,986.

To all wtom'z't may concern.'

Be it knownthat I, VILLIAM S. HARLEY, a

- citizen of the United States, and resident of Milwaukee, in thecountyof Milwaukee and tate of l/Visconsin, have invented. certain newand useful Improvements in Motorcycle-'Windshields; and I do herebydeclare that the following is a full, clear,kand exact descriptionthereof.

My invention relates to new and useful improvements in windshields, moreparticularly of'that type which is adapted for securement to amotorcycle structure for shielding the body and head of the rider.

It is in general the object of my invention to simplify and otherwiseimprove the struc- Y ture and to increase the degree of protection andthe convenience aifordedbydevices of this character.

A further object resides in the provision of Y a windshield which may bereadily attached to a motorcycle handle bar or other support structureand which when attached may be shifted to permit desired freedom ofmovement of the person whom it is intended to shield.

.A still further object resides in the provision of a windshieldstructure adapted for securement to the handle bar structure of amotorcycle whereby to effect a most snug relation to the rider andwherein provision is made for procuring a complete shielding actionwithout interfering with steering. movement of the handle bars.

i With the above and other objects and ad-v vantages in view, which willbe apparent as the description proceeds, my invention re- I sides moreparticularly in the novel features of construction, combination andarrangement of parts as hereinafter more particu larly described anddefined by the appended claims.

In the accompanying drawings:

Figure 1 is a rear elevation view of my improved. windshield structureapplied to the handle bars of a motorcycle, contiguous portions of themotorcycle structure being shown in section. y

Fig. 2 is an elevational view of one of the pivotV connections of theshield, looking toward the outer side thereof.

Fig. 3 is a similar view looking toward l nthe inner side thereof.

Y distance below the handle bars. f

improved windshield structure comprises a main frame formed in thepresent instance of a length of channel iron 141 bent in' invertedUshape, the intermediate portions of the legs of this bar beingconnected" by a brace iod 15 which incidentally affords a convenienthandle in grasping the shield to shift it as will be later described.The ends of the channel frame bar 14 have frictional pivotal connectionwith the handle bars 10, pivotal movement of the frame inwardly beingadjustably limited.

To effect this pivotal connection, a friction head disk 16 is secured toeach frame leg by a shank 17 secured within the channel 4of the leg anda `pivot bolt 17 is passed through the disk, said bolt being carried ona clamp head 18 having a concaved boss 19 thereon adapted to engageagainst the handle bar, said boss being embraced by the legs of aU-shaped clamping strap 20 extending rabout the handle bar and havingits ends laterally turned for the reception of bolts 21 extending fromthe `clamping head, nuts 22 being provided on said bolts for drawing theclamping strap to securely fasten the head 18 to the handle bar. It isnoted that the concavity of the boss 19 itsthe curved surface of thehandle bar and inasmuch as the handle bars of a vehicle are relativelyinclined, said boss is tapered longitudinally of the handle bar to whichit is attached V"whereby to dispose the pivot aXis of the connection inalinement with the pivot axis of the 'connection for the other handlebar. A friction washer 23 is disposed o n the bolt 17 between thefriction head 16 and the clamp head 18 and pressure is procured betweenthe contacting faces of the heads and washer by a mushroom spring 24cmthe threaded on the bolt and thus holding all boltwoutwardly of theframe headv 16, 1V

spring being engaged by a lock nut 25 of the parts in assembledrelation.

For adj ustably limiting pivotal movement of the friction head16 in onedirection, downwardly extending abutment arm 26 -is formed thereonengageable against the head of a stop screw 27 which is threaded in ablock 28 having a shank 29 passed through a depending arm .30 on theclamp head, saidV shank being securedin the arm by a nut 31 threadedthereon.

. The body material of the windshield, com-Y posed preferably of asinglesheet 32 of suitable heavy material is .secured to the frame throughoutits'lengtli in any suitable manner, saidbodyhsheet being provided in itsupper portion with a sight window 33. The body sheet is flared outwardlyat 34; from the lower Y portion of the frame to form Wings adapted f toprotect the hands and forearms of the rider in grasping the handle bars,and at the Y lowerend of the frame the body material is slit inwardlyfrom its side edges to receive Y the handle bars, the material at thesides of the slitwbeing lapped as indicated at l35 and connected by aconventional bolt snatch fastener 36 or other suitable connecting edgesof the shield plates 12 by snap fasteners 37 or other suitable securingmeans, thus affording free folds of material 38 between the shieldplates and the handle bars, said folds being taperingly increased inwidth f toward the sidesof the sheet, thus permitting free steering'movement of the handle bars.

while at the same time affording a complete protection for the rider.

In certain instances, as in cranking the engine, it isdesirable for thevrider to lean forwardly of the motorcycle, and a pivotalmounting of thewindshield is provided to accommodate this desired freedom ofmovement,it being noted that the frictional action setup by the spring 24 andwasher 23 serves to hold the shield in any .desired forwardly tiltedposition, while inward swingingmovement of the shield ypast a certainpredeter-- mined limit is prevented by abutment ofthe arms 26 of thepivot connections with the I adjustable vstop screws 27.

My improved-windshield may also be assd- -ciated with a `sidecarstructure as shown in Fig. 6, rthe forward tilting movement of theshield facilitating entrance and exit of a per- .son with respectV tothe side car. In this structure, the ends of the frame legs Haareinwardly' offset .and are each ysecured. to a friction yhead 16aconnectedbya bolt 17 l with y a stationary friction head 18a which isse- .'cured by lateral arms 39 to the sides of the side-car body VThevlower end of the body sheet 32a is secured at 41 in any suitablemannertoithe.side-car body and yields upon tilting' movement of theframe.

While I have shown and described the preferred embodiment lof vmyinvention, it will beappreciated that, to meet differing conditions ofuse, various changes and modifications of structure may be employedwithout departing inany manner from the spirit ofmy invention. Y
